  DuPont ™  Krytox  ®  NRT LUBRICANTS FOR REACTIVE GAS SERVICE PRODUCT DATA SHEET  DuPont ™  Krytox ®  NRT greases and oils deliver nonreactive, non-flammable, long-lasting performance even under the demanding temperatures and pressures of reactive gas service. Krytox ®  NRT lubricants are compatible with oxygen and other reactive chemicals and are extremely resistant to water washout. Krytox ®  NRT lubricants are also compatible with polymers used in seals, O-rings and valves.The superior film-forming capability of Krytox ®  provides a thick oil layer that reduces friction and wear, extending equipment life in severe duty applications. The nonoxidizing nature of the oils makes the greases last longer. The oils don’t gum up as they age, so they won’t harden the greases and cause catastrophic failure. Krytox ®  is a perfluoropolyether (PFPE) — also called perfluoroalkylether (PFAE) or perfluoropolyalkylether (PFPAE). Many of the Krytox ®  NRT greases are thickened with a unique polytetrafluoroethylene (PTFE) with the formula (CF 2 -CF 2 )n. This special high efficiency thickener has a melting point of 325°C (617°F) and has low molecular weight and submicron (0.2 m) particle size. Krytox ®  NRT 8900  grease has been formulated for use in cold to ambient conditions, and is recommended as a cost-effective valve packing and seal lubricant for O-rings. Krytox ®  NRT 8904  and 8906  provide excellent lubrication options for valves, regulators, seals, and pump and motor bearings at a wide range of operating conditions. Krytox ®  NRT 8906A  provides rust protection at ambient temperatures, corrosion protection at high temperatures, and antiwear protection. This white grease, containing a patented soluble anti-corrosion additive, is designed for bearing applications where anti-corrosion protection is required. Krytox ®  NRT 8908  grease is a special high-pressure oxygen paste with excellent lubrication over a broad temperature range. This product has been formulated with special oils and thickeners for use in the high-pressure oxygen industry. Krytox ®  NRT 8908 received a rating of 350 bar at 60°C in the BAM oxygen reactivity test, making it a great choice for valves in high pressure service. Krytox ®  NRT 8950  is an extreme high-temperature grease with low oil evaporation. The special non-melting high temperature thickener in Krytox ®  NRT 8950 also provides extreme pressure properties and works as a solid lubricant if the base oil is depleted. The base oil provides good viscosity and lower evaporation at high temperatures. The grease is slightly tacky and will provide extra bonding to the surface. Krytox ®  NRT 8950 received a rating of 180 bar at 60°C in the BAM oxygen reactivity test. Krytox ®  NRT 8990  is a linear PFPE grease providing low volatility characteristics for longer lubricant life. The base oil has a high viscosity index to provide effective lubrication over a wider temperature range, making it a great choice for liquid oxygen service. Krytox ®  NRT 8990 is formulated using a patented soluble anti-corrosion additive that helps reduce noise, rusting, and wear, thus extending grease, bearing and component life. Krytox ®  NRT PLSS  is recommended for use in applications requiring an H-1 rated lubricant. Krytox ®  NRT 8805  is a clear, colorless oil for use in vacuum pumps and oxygen compressors. It has been precisely distilled to provide low vapor pressures and provide superior performance when compared to conventional vacuum pump oils which may cause safety, waste disposal, and maintenance problems. Krytox ®  NRT 8805 also contains a patented soluble additive to offer antirust protection and improved performance properties.  Copyright © 2007 DuPont.
